Paper Abstract

In the hybrid fiber-coax (HFC) architecture, the coax is a shared medium to which the network interface units (NIUs) of different end-users are attached for accessing a diversity of network services. To analyze the traffic carrying capacities of the coax, a C-i--i- object-oriented simulation tool has been developed. This paper reports on the use of this tool and analytical techniques in the investigation of several key traffic issues: . use of call packing to improve upstream bandwidth efficiency . impact of proximity restriction associated with frequency hopping on blocking S design of time-slot assignment algorithms . downstream load balancing . effectof call retries
